DEVICE FOR CHARGING FURNACES.

SPECIFICATION forming part of Letters Patent No. 429,200, dated June 3, 1890.

Application filed March 13, 1890. Serial No. 343,716. (No model.)

To all whom it may concern:

Be it known that I, JOHN M. PAGNOUL, a subject of the King of the Belgians, residing at Bridgeton, county of Cumberland, State of New Jersey, have invented a certain new and useful Device for Charging Glass-Furnaces, of which the following; is a true and exact describtion, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to devices by which the charge of batch is inserted into a tank glass-furnace.

Heretofore, so far as I am aware, the batch has been simply dumped through the charge hole or door of the furnace, and the workmen in charging the furnace were compelled to come close to the open door, where they were subjected to the intense heat issuing from it.

My object is to enable the batch to be dumped into the furnace at a point well within the same and without requiring the workmen to approach very close to the open chargingdoor; and the leading feature of my invention consists in combining with a truck abeam having aprojecting end adapted to enter the charging-door of the furnace, a dumping-box secured on the end of this beam, and means for discharging said box when within the furnace.

The construction of my device will be best understood as described in connection with the drawings in which it is illustrated, and the novel features which I desire to protect by Letters Patent are hereinafter clearly pointed out in the claims.

In the drawings, Figure 1 is an elevation showing my device in its preferred form and in connection with the tank glassfurnace partially illustrated in section. Fig. 2 is a cross-sectional view taken on the line :0 a: of Fig. 1, looking away from the furnace. Fig. 3 is a side elevation of amodification of my device; Fig. 4., an end view of the brace or truss connecting the two beams shown in Fig. 3, and Fig. 5 a side elevation of still another modification of my device.

A is the tank glass-furl] ace; 0,, its charging door.

B indicates tracks which are arranged in the plane of the charging-door of the furnace and outside of the same, as shown.

0 indicates a truck or carriage, the wheels 0 of which move upon the tracks B, and which supports a beam D, a portion of which (indicated by the letter D is arranged in line with the charging-door of the furnace and adapted to enter the said door. Preferably that portion of the beam which is supported directly upon the truck is made to roll upon the same, resting in the groove of rolls J, (see Fig. 2;) but the beam may be attached to as well as supported on the truck, if desired.

Upon the end of the beam which is extended toward the charging-door of the furnace I secure a dumping-box F in any convenient way, and I provide said box with connections or mechanism whereby it can be discharged of its lead, and for which purpose, of course, any of the well-known devices used in connection with dumping-boxes may be used.

In'the drawings I have illustrated a simple device consisting of a shaft E, supported in bearings d d upon the beam D, and to the end of which projecting beyond the end D of the beam I secure the box F, while to the other end of said shaft I attach a handle e. The dumping-box is so secured to the shaft that it will normally remain in an upright position, but can easilybe turned over bythe operator turning the shaft by means of its handle 6. here, as in Fig. 1, the beam which supports the charging-box rests upon a truck moving on tracks situated below the door of the furnace, the weight of the box on the long projecting end D of the beam is counteracted by means of a counter-weight G, secured upon the opposite end of the beam. In this construction, which, by reason of its simplicity, I prefer to use, the beam occupies a considerable amount of space upon the floor of the building in which the furnace is situated. here this is objectionable the space occupied can be diminished by means of the modified constructions shown in Figs. 3 and 5, in both of which figures the track B is supported above the level of the top of the furnace.

In the construction indicated in Fig. 3 a beam (marked D) is supported by the truck 0 and connected by means of a truss or brace D with a parallel beam D arranged in line with the charging-door of the furnace, and to the end I) of which, as in Fig. 1, the dumping-box I is secured. The truss or brace I) in this construction must of course be strong and rigid, and can well be constructed as shown in the drawings, Figs. 3 and l. The beam D is made up of two angle-irons ll. ll, secured together by rivets or blocks, and to the inside of which are riveted plates 7: 71, to which plates two pairs of angle-irons 7L and 71' are secured, as shown, the beam I) being connected and supported by the lower ends of these angle-irons. In order to stiffen the brace or truss, cross-bars 71." may properly be riveted to it.

In the construction shown in Fig. 3, as in that shown in Fig. 1, a counter-weight G should be used to counterbalance the weight of the dumping-box.

In Fig. 5 I have shown a construction in which a beam C rests upon the axles of the wheels 0 c and has depending from it links I I, which are attached toand support a beam 1), said beam D being connected with a beam D by means of a brace or truss I), as in llig. 3. In this construction the beam 0 rolls on the axles of the wheels which move upon the track, and has lugs 0 which come in contact with the said axles and prevent further movement of the beam C upon the same in one direction, while the links I serve a similar purpose when the apparatus is moved in the other direction. \Vhen constructed in this way, a counter-weight need not be used, and, if desired, the connection between the beam 0 and the beam 1) may be made by a single link or chain; and if so, if we lengthen beam. D and place a counterweight on the oil side of the single link or chain, the whole apparatus revolves around this point.

Having now described my invention, what I claim as new, and desire to secure by Let ters Patent, is

1. As a device for charging glass-furnaces, a truck, a beam supported on said truck and adapted to enter the charging-door of a glassfurnace, a dumping-box secured at the end of the beam, and means for discharging said box of its load.

2. As a device for charging glass-furnaces, a truck, a beam supported on said truck and adapted to enter the charging-door of a glassfurnaee, a shaft journaled and supported on said beam, and a dumping-box attached to the end of said shaft.

3. In combination with a tank glass-furnace, tracks arranged outside of the same in the plane of its charging-door, a truck moving on said tracks, a beam supported on said truck in line with the chargingdoor of the furnace, a dumping-box secured at the end of said beam, and means for discharging said box.

4. In combinatiml with a tank glass-furnace, tracks arranged outside of the same in the plane of its charging-door, a truck movin g on said tracks, a beam supported on said truck in line with the charging-door of the furnace, a dumping-box secured at the end of said beam, a counter-weight arranged to balance the weight of the loaded dumpingbox, and means for discharging said box, all substantially as and for the purpose specified.

5. In combination with a tank glass-furnace, tracks arranged below and in the plane of the charging-door of the furnace, a truck moving on said tracks, a beam 1), supported on said truck arranged in line with the chargin g-door, a d umping-box supported on the end of said beam extending toward the furnace, a counter-weight supported on the other end of said beam, and means for discharging said box, all substantiallyas and for thepurpose specified.
